Описание (английский):

ISO 21627-3:2009 specifies a method for the determination of the total amount of chlorine in epoxy resins. The chlorine measured by this method, referred to as total chlorine, includes saponifiable organic chlorine and inorganic chlorine.

Abstract

Overview

Key topics and technical requirements

Scope and definition: Total chlorine is defined as the amount of chlorine measurable by this method and includes 1,2- and 1,3-chlorohydrins and chloro‑glycidyl derivatives plus inorganic chloride.
Principle: Dissolve a test portion in diethylene glycol monobutyl ether, saponify by refluxing with an alcoholic potassium hydroxide solution (KOH in 1,2‑propanediol), then determine chloride by potentiometric titration with standardized silver nitrate.
Reagents and concentrations: The standard specifies analytical-grade reagents and water (ISO 3696 grade). It gives preparation and standardization procedures for 0.1 mol/L and 0.01 mol/L AgNO3 titrants, and details for KOH solution in 1,2‑propanediol and solvents (diethylene glycol monobutyl ether, acetone, glacial acetic acid).
Apparatus: Requires potentiometric titration setup (silver electrode and reference), analytical balance (0.1 mg), reflux apparatus and heating (hotplate/oil bath capable >200 °C), magnetic stirring and common volumetric glassware.
Procedure highlights: Weigh a test portion (selected to give an appropriate chlorine mass), dissolve, add KOH solution, reflux ~10 min, cool, transfer and acid-wash, then titrate with AgNO3. Perform a blank and calculate chlorine content from titrant volume.
Safety & quality: Users should follow normal laboratory safety and use specified reagent grades and water purity.

Applications and users

Quality control laboratories in epoxy resin manufacturing to monitor chlorine impurities that can affect cured resin properties.
Materials testing and certification bodies assessing compliance with product specifications or customer requirements.
R&D teams analyzing by‑products from epichlorohydrin-based production routes.
Regulatory and procurement professionals who need standardized test data for material acceptance.

Keywords: epoxy resins, total chlorine, chlorine content determination, potentiometric titration, silver nitrate titration, saponifiable chlorine, inorganic chlorine, ISO 21627-3:2009, CEN.
